Hey madkins, beautiful looking rig!
Sorry to hear you're finding some things that seem to have not been tweaked just right when the rig was built. Did the PO say they just did a full restoration, including replacing a lot of rusted body panels? I'm hoping I'm not right, but if so they may have welded the pillars on incorrectly.
Hopefully member JamesRoney will see this and chime in. We have some fairly current discussions (maybe it was you?) going on just recently highlighting the issues with lining up the A-pillar just right to get the cowl, windshield, pillar, fender skirts, fenders, hood, grille and doors to line up just right.
Basically trying to tweak any one of those other things can put the others further off if the A-pillar is installed incorrectly.
Some basic things to look at first though, would be the body mount insulators. Are they new? Are they old rubber and sagged out? If they look old, or even if they're new, measure them and see if they are 3/4" tall or not. More or less can indicate other things. Even Ford added shims to the body mounts during assembly to correct things like door gaps and such.
Not as extreme as yours might be, but some.
And your hard top may not be pulled out far enough as well. Everything has to be working together. Windshield frame angle, top location before it's bolted tight, A-pillar placement, body mount heights, etc.
Hopefully it's simple adjustments. But time will tell where the problem is located.
have you posted up other pics of your bronco elsewhere? Be great to see some more shots.
Oh, and don't overlook poor fitting door seals!
Good luck.
Paul
